Title: Automatic regulation of metal level in - ingot moulds
IPC: B22D11/18
Filed: 1970-08-12
Abstract: The apparatus comprises a computer with a reversible counter connected to an actuating mechanism by an impulse transmitter transforming the movement of the actuating mechanism into a discontinuous signal, and to a unit set at zero belonging to the reversible counter. The latter is also connected to a decoding device, by which the number of impulses determining the extreme position of the distribution valve in established. In its turn, the decoding device is connected to the actuating mechanism by two electronic units limiting the degree of opening and closure and putting the actuating mechanism out of circuit by a control unit when the distribution valve is in extreme positions corresponding to those established by the decoding device. A programming unit connected to the control unit enables the former to isolate the actuating mechanism from an electronic regulator from time to time, and to move the distribution valve to its extreme position. The programming unit locks the unit set at zero belonging to the reversible counter.

Title: Pincer action tool positioning shaft rings - forces wedge embodying hard metal needles into circumference gap
IPC: B25B27/20
Filed: 1973-05-29
Abstract: Pincer action tool opens collars (ie spring type gripping shafts) prior to positioning on shaft by forcing wedge embodying two hard metal needles into the circumferential gap: the constitution of the needles obviating binding. The tool mobilises a wedge (5) laterally to effect expansion of a collar and has working parts of hard metal and an eclipsable counter stop (6) which in a first position maintains the collar open and in the elipsed position releases it. The one leg (1) of the pincer terminates in a U (2) to support the collar and the other leg (3) through lever action enforces wedge motion: hand pressure converging pincer handles initially gradually opening the collar until the stop (6) is engaged, whence light pressure maintains the collar open, until finally eclipsing of the stop releases the collar at the desired location.

Title: Diaphragm pump - chambers separated by diaphragm handling fluid and gas transmitting driving impulses
IPC: F04B49/12
Filed: 1974-02-28
Abstract: The pump comprises a chamber with inlet and outlet (20, 24, 25) for a first fluid or gas, which is delivered in measured quantities under the effect of a second fluid or gas delivered by impulses into a second chamber (21), also with inlet and outlet.

Filed: 1974-12-20
Abstract: Prods. contain diamonds with a size 1 mm which are mixed with a metal-carbide and hot pressed in graphite moulds at a temp. ca 1800 degrees C. Heating for pressing consists of heating the mould to 1200 degrees C by high-frequency induction at a rate of 1000-1100 degrees C per minute, followed by heating to the final sintering temp. at 3000-6000 degrees per minute by resistance heating of the carbide-diamond mixt. in addn. to heating the mould by induction.
